Find the differences in the room

The essence of the game is that you will be a limited amount of time to find all the differences. Once you start the game, you will see two small pictures, depicting a girl in the woods. You need to be viewing the good point of difference between them. To cope with this task, you need to find every one of the differences. If you do not find at least one difference, you unfortunately lose and you have to start the game from the beginning.
